PHP does not validate the relationship between the soap.wsdl_cache_dir
directive and the open_basedir directive, which allows remote attackers to
bypass intended access restrictions by triggering the creation of cached
SOAP WSDL files in an arbitrary directory.

The SOAP parser in PHP allows remote attackers to read arbitrary files
via a SOAP WSDL file containing an XML external entity declaration in
conjunction with an entity reference, related to an XML External Entity
(XXE) issue in the soap_xmlParseFile and soap_xmlParseMemory functions.

A Heap-based buffer overflow flaw was found in the php
quoted_printable_encode() function. A remote attacker could use
this flaw to cause php to crash or execute arbirary code with the
permission of the user running php

Integer overflow in the SdnToJewish function in jewish.c
in the Calendar component in PHP before 5.3.26 and 5.4.x
before 5.4.16 allows context-dependent attackers to cause a
denial of service (application hang) via a large argument to
the jdtojewish function.
